How can I tell my iPhone 12 is fast charging? Any notifications on the phone to look for?

Hello fabian1313,

We understand you'd like to know if there is a way to confirm your iPhone is using fast charge.

There isn't a notification or alert to indicate your iPhone is using fast charge. When you use fast charge with supported iPhone models, you can recharge your iPhone up to 50 percent battery in around 30 minutes. The time that it takes to recharge can help determine if your iPhone is fast charging.

Please see how to Fast charge your iPhone for additional details on which type of power adapters you can use. You can also learn more About the Apple USB-C to Lightning Cable, as well as Power adapters for iPhone.

If you'd like to charge your iPhone 12 wirelessly, please see How to use your MagSafe Charger with iPhone 12 models. We also have information on How to wirelessly charge your iPhone with Qi-certified charging accessories.
